how does a water fluotation mill work for gold

Gold Extraction & Recovery Processes

Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

Natural Surfactants for Flotation Deinking in Paper Recycling

The surfactant can exist at the ink-water interface, the ink-air interface and the air-water interface, changing the surface characteristics. There has been some recent interest in flotation processes in which the surfactant is sprayed on the top of the flotation cell rather than mixed with the pulp prior to flotation (DeLozier et al, 2005).
